REMOVABLE manna: roa PRINTING FORMS.

Application filed July 11, 1924:. Serial No. 725,369.

17 all whom it may concern:

Be it known that I, CLIFTON CHISHOLM, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and useful Improvement in a Removable Insert for Printing Forms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a simple and inexpensive device for holding a few lines of printing members, adapted for ready mounting in a printing machine. The invention is particularly useful where many impressions are taken from a form, a minor portion of which is changed from time to time.

A more particular use of this invention is in connection with a multigraph having a rotary drum on which are mounted rows of type. My removable insert is adapted for ready mounting on such railed drum and adds to the type form a few lines adapted to printing in conjunction therewith, but

readily changed without disturbing the type on the drum.

The invention hereinafter is more fully explained in connection with the drawings and the essential novel characteristics are summarized in the claims.

In the drawings Fig.1 is an end elevation, partly broken away, of a multigraph drum, equipped with rows of individual type and my removable insert: Fig. 2 is a fragmentary plan of such drum so equipped: Fig. 3 is a cross section through the removable insert device: Fig. 4 is a perspective of the holder member of the removable insert, which is directly mounted on the drumz'Fig. 5 is a perspective of the lock for the holder.

In Figs. 1 and 2, A indicates a multigraph drum having about its periphery parallel rails a with overhanging edges. B indicates short type grooved on its opposite sides and adapted to be slid endwise of the rails into the space between them, such type being retained in place by the overhanging heads of the rails, and, if desired, prevented from laterally shifting by stop plugs or clips, 0 (Fig. 2) mounted in the channels.

The parts described constitute usual multi graph equipment with which my removable insert is designed to cooperate,

My removable insert comprises a holder adapted for ready mounting on the drum,

. aassutn a plate with upwardly extending projections mounted on the holder, and embossed printing strips mounted on the plate. These parts have such thickness and are so formed that the face of the printing characters on the embossed strip isthe same radial distance from the axis of the drum as the face of the type B.

The holder for the removable insert, designated 10, comprises a plate having on its underside means for holding it on the drum and on ts upperside means for holding the plate which carries the strips. As shown in Flgs. 3 and 4, the holder plate has on its underside longitudinal rails 11 which are Ol lDVGTtBCl T-shape in cross section. These rails may be welded or otherwise secured to the plate 10. This plate has its edges curled under upwardly and inwardly to provide the hooked flanges 12. Such a holder may be readily mounted on the multigraph drum by being slid lengthwise thereof, the rails 11 being so positioned on the plate 10 that they register with channels between some of the rails a 011 the drum.

The plate which is mounted on the holder and carries the embossed strips is designated 20. This plate has parallel rows of upwardly projecting buttons 21 stamped up from the plate and connected with it in direction ofthe row, but disconnected at the edges, which project freely toward adjacent rows. Such a plate is shown, described, and claimed inthe patent to IV. J. Deming, #1,l88,58& issued Dec. 12, 1922, to The American Multigraph Company. In addition to the stamped up buttons, the plate preferably has also upstanding corrugations 22 between the buttons, which act to stiffen the plate and with the buttons provide a continuous support for the embossed strips. This feature is covered in Patent #1,438,- 582 of B. J. Craig, issued Dec. 12, 1922 to The American Multigraph Company.

The embossed strips are designated in Figs. 1, 2, and 3. Each strip is a metal member having printing characters on it embossed upwardly from the underside of the strip. The edges of the strip are curled or flanged downwardly and inwardly as shown in 31. Such an embossed strip may he slid endwise over the row of buttons and the strip desired, I may form an abutinenfi'lfo these strips at one end by inserting a flat flexible strip of metal transversely of the rows through the space beneath aligned-buttons. Sacha button strip is shown at .23 in Fig. 2 and is claimed in my co-pending application #673,418, filed Nov.

It will be seen that the embossed strips, made by some suitable machine, may be quickly mounted and secured on the plate 20. Likewise, such plate with the strips may be quickly mounted in the holder 10 and the holder 10 may be quicklyv mounted on the multigraph drum,

If desired,- the holder may be prevented from shifting. laterally on the drum by the useiof the usual plugs .or clips such as shown at C for locking the type lines. However, I regarded it preferable to provide a special lock: on the holder 10. I have shown such lock. in the form of ascrew 40, the shank of which passes through ahole in the holder, and a nutkll threaded thereon and occupying oneof the channels of the drum and prevented from rotating .by engagement with the side walls of adjacent. rails of the drum.

Such screw isso located inthe plate 10 that the nut aligns with. one of the channels.

when the rails 11 aligns with other channels and such holder. is I slid into place .on the drum whenthescrew is turned bya screw driver, drum. The head or the screw pcrt'ormsair other function, formingan abutment fortho plate 2O.v Accordingly, by properly positioning the holder on the .drum,,the plate, shoved dengthwise against the screw head comes into the proper position ,to have the embossed strips held by the positioning strip 23. in proper registration with the rest of.

theform ,on the drum.

Ihave found it usually ,suliicient to lock the holder inposition and use the head. of the screw ltO as. anabutment for theplate,

the latter. fitting the overl ianging edges 12 y of the holder .with sufficientsnugness so that it does not becomedisplaced in operation of the machine. However, if desired, a suitable clip may beinsertedin oneof the channels at the other ,end of the holder and bear against that end-of the,plate and thuspositivelyapreventits shiftingin that direction.

It will be noted that. theremovable insert as described isadapted for mounting on a railed member whether .the latter. be a rotary-drum iorca fiat bed. Ifthe device is the [holder becomes clamped to the used 011 a flat bed the holder plate 10 is made flatand both rails 11 have. their webs vertical. When the holder is intended for mounting on a drum the plate 10 is preferably curved concentrically of the drum sur face and the rails 11 are positioned radially thereon, as shown in Figs. 3 and Itv ill be seen that the same plate 20 may be used over and over again with different, embossed lines thereon. The ordinary equipment for this attachment may well comprise one holder 10, several platesZO and the requisiteembossed lines, these enibossed lines to be made up according .to the different matter to be inserted and mounted on difi'erent plates 20. when the body of the form is on the drum and the holder locked in placein proper position with relation thereto, one plate '20 with its embossed stripsmay he slid :into place in theholder and thedesired number otcopies run off,

the machine stopped, and the plate20-with its strips slid'out and another platev with str ps substituted. The plates and strips occupy a small spaceand may be stored in assembled condition tonsubsequent use,.or

on .said plate.
